| 中文摘要: |
| 贵州遵义锰矿是我国二叠纪重要的锰矿床类型之一。近年来，遵义锰矿浅部资源日趋枯竭，找矿工作从浅部转向了深部，对隐伏锰矿的找矿迫在眉睫。在找寻隐伏锰矿中，原有的找矿勘查方法遇到了瓶颈，本文在结合大量地质研究的基础上，基于深部地层、构造、含矿岩系的电性差异，在研究区首次应用音频大地电磁法对隐伏锰矿体开展探索研究。研究发现，通过精细化的数据反演，该方法能够较好地反映研究区深部地层、构造及含矿岩系的展布特征，并部署钻探验证，所揭露的岩矿层位、构造特征和音频大地电磁法解译吻合程度较高。该方法可推广到研究区及其同类型区域的锰矿找矿勘查中，是锰矿找矿预测的有效方法之一。 |
| 英文摘要: |
| Zunyi manganese deposit in Guizhou is one of the important manganese deposits in Permian in China. In recent years, the shallow resources of Zunyi Manganese deposit are becoming increasingly exhausted, and the prospecting work has shifted from shallow to deep. The prospecting for concealed manganese deposit is imminent. In the search for concealed manganese ore, the original prospecting and exploration methods have encountered a bottleneck. Based on a large number of geological studies, due to the electrical differences of deep strata, structures and ore bearing rock series, audio magnetotelluric method is used to explore and study the concealed manganese ore body for the first time in the study area. It is found that through refined data inversion, this method can better reflect the distribution characteristics of deep strata, structures and ore bearing rock series in the study area, and deploy drilling verification. The revealed rock and ore horizons, structural characteristics and audio magnetotelluric interpretation are in good agreement. This method can be extended to the manganese ore prospecting and exploration in the study area and its similar areas. It is one of the effective methods for manganese ore prospecting and prediction. |
